Part of an international non-profit community service network, Toronto Master Gardeners are a group of more than 130 trained horticulturists who volunteer their time to provide advice to home gardeners in the Toronto area.

All Master Gardeners have successfully completed university horticultural studies and must meet ongoing continuing education requirements to make sure that our advice to gardeners is based on current horticultural knowledge.

History and Organization

The volunteer Toronto Master Gardeners have been advising and helping solve problems for Toronto gardeners since January 1988.

The Toronto Master Gardeners are part of the province-wide Master Gardeners of Ontario Inc. (MGOI). There are 38 local Master Gardener groups in Ontario, focusing on sustainable gardening information for the public. There are also Master Gardener groups in many provinces, most states, and in some international locations. More information may be found on the MGOI website.

For answers to horticultural questions, post your question on the ‘Ask a Master Gardener‘ page on this site. Or, you may leave a detailed message on (416) 397-1345 and a volunteer will call you back.
